1. A sensor structure comprisinga support frame (18) having a cavity defined by adjacent inwardly facing sides which join each other at inwardly facing junctures,a mass (16) disposed within said cavity, said mass having outwardly facing sides which intersect each other at outwardly facing junctures such that each of said outwardly facing sides of said mass is parallel and corresponds to one of said inwardly facing sides of said support frame, andeach of said junctures of said outwardly facing sides of said mass (16) faces and corresponds to one of said inwardly facing junctures of said support frame (18);

  • said mass being dimensioned and arranged in said cavity so as to produce a peripheral space defined between said outwardly facing sides of said mass and said inwardly facing sides of the support frame; and

    a plurality of springs (32) with each of said springs having only two connection ends, each of said springs having a first leg having a first connection end of said two connection ends and a second end, each of said spring having a second leg having a first end and a second connection end of said two connection ends, said first leg being disposed at an angle with respect to said second leg and having said second end joined to said first end of said second leg at a junction of a junction region where said second end of said first leg joins with said first end of said second leg, said junction region being characterized by an elbow shape, each of said springs placed in said peripheral space and (i) is connected at said first (44) end of said two connection ends to one of said outwardly facing sides of said mass (16), (ii) has said junction region placed around one of said outwardly facing junctures of two of said outwardly facing sides of said mass, and (iii) connects at said second connection end (42) to one of said inwardly facing sides of said support frame, the springs for mounting said mass for movement relative to said support frame.
